--- Quote from: zoltm on May 28, 2012, 05:20:02 pm ---To share a number of the internal shoots. It looks like it's NOT a 100KHz solution that based on the Cyrustek chipset. It looks like a FPGA based solution. --- End quote --- Has the build quality of a non-china meter ... that is just awesome, it's the applent right ? The Tonghui(i think) kinds of reminds me of the UNI-T case design, the only weak point is the micro usb connector which can ingest dust, they should have used a soft rubber cover over the jack anyways |

zoltm, that's not the Applent (ridiculous name) or Mastech in those pictures. It's a Tonghui. EDIT: Never mind, I was only looking at the top two pictures. |

--- Quote from: Aurora on March 31, 2012, 08:54:45 am --- I also downloaded the IET Labs DE5000 manual as that unit uses the same chipset so is basically the same but with a different front panel ;) IET rewrote the manual to improve it. I attach the chipset data sheet. The IET DE5000 manual is available here: http://www.ietlabs.com/de5000-lcr-meter.html Kind Regards Aurora --- End quote --- I just ordered a Mastech here http://www.ebay.de/itm/MS5308-Portable-Handheld-LCR-Meter-RS232-100Khz-fit-FLUKE-dual-display-UK-ship-/220926501998 But the de5000 manual url on the ietlabs.com site is broken (at least for me) Could someone upload it here or contact me ? Edit: Oopz i tried the software url. The manual url works here : http://www.ietlabs.com/pdf/Manuals/DE_5000_im.pdf TIA /Bingo |
| The Electrician:
A couple of deficiencies exhibited by the low cost LCR meters as I see it are the lack of adjustable drive level and too few measurement frequencies. The older meter: http://www.ebay.com/itm/BK-Precision-885-Synthesized-In-Circuit-LCR-ESR-Meter-/190680646307?pt=LH_DefaultDomain_0&hash=item2c6573c2a3 has 3 different drive levels; one sufficiently low to avoid turning on semiconductor junctions. This is the 10 kHz max version and sells new for around US$500. There is a 100 kHz max version: http://www.ebay.com/itm/BK-Precision-886-Synthesized-In-Circuit-LCR-ESR-meter-/190681758749?pt=LH_DefaultDomain_0&hash=item2c6584bc1d that goes for about US$700+. Most of the 100 kHz capable meters seem to be up there in price. I notice that a Chinese meter: http://www.ebay.com/itm/LCZ1062-1062-LCZ-Meter-LCR-Tester-LED-Display-Digital-Bridge-1V-200KHZ-/320914942343?pt=LH_DefaultDomain_0&hash=item4ab8056987 has shown up on eBay. It's not hand held, but it's much more capable than the typical hand held with 100 kHz capability. It has a 40 Hz to 200 kHz measurement range comprising 30 frequencies in that range, with 10 mV to 1 V drive level range and .1% basic accuracy. It has the traditional 4 terminal interface and the image shows kelvin clips in use. It costs US$594.99 with free shipping to the U.S.; this is not much more than a 100 kHz capable hand held unit. This would be an astounding bargain if the performance is at all good. It's not as capable as the very expensive instruments (Agilent, Wayne-Kerr, etc.) some of us have access to at work, but only US$600? Wow! edit: Here's another one I just saw: http://www.ebay.com/itm/200KHZ-DIGITAL-BENCHTOP-LCR-RCL-LCZ-METER-TESTER-ESR-DC-BIAS-AXIAL-FIXTURE-/261020859321?pt=LH_DefaultDomain_3&hash=item3cc60e3bb9 It's not as pretty, but appears to have similar capability and sells for about US$470, shipping not included. Notice that it has provision to apply up to 35 volt bias. |

I found a lot of references to Zentech, but no info. It looks a lot like a Chroma unit. http://www.chromaate.com/product/1061A_1062A_1075_Precision_LCR_Meter.htm Anyone have opinions on the ebay unit? Or, info about Zentech and Chroma? |
